Attendee Feedback

DSEI Japan really played its part in helping the Japanese government win a successful contract with the Australian navy for 6.5 billion Australian frigate programme. The meetings and the live demonstrations held at the show were vital for the final bid's success.

Japanese Ministry of Defence

It was a very energetic and dynamic event. In particular, not only was it a valuable opportunity for Japanese manufacturers to showcase their presence to other countries, but I also found it meaningful to learn about products from European and other regional manufacturers that are not very familiar in Japan.

This was Fujitsu’s first time exhibiting at a defence show, and it was a great opportunity for exposure. We were able to connect with many visitors and potential partners from overseas, which supports our broader goal of expanding internationally. Building relationships abroad also helps us bring fresh ideas to the table and contribute new perspectives to the industry.

Thank you for bringing the Prime Minister of Japan to our Boeing stand. Post the PM's visit, I spoke directly with the Boeing Global CEO, who expressed his joy and gratitude on achieving such a great visit.

This was our second time at DSEI Japan, and we saw significantly more traffic than before. Our goal was to expand our brand and show the world all that SAAB has to offer. One of the highlights was the strong media presence, and we were proud to have great visibility with our customers and wider audience.

DSEI Japan gave us a valuable opportunity to strengthen existing relationships and explore potential partnerships at various levels. It also offered some useful insight into current industry developments and allowed us to have meaningful conversations with the right people.

You can understand the state of the art military equipment, technology, concept. Some of them are very important when we consider strategy. In short, everything is necessary to do our business as a think tanker.
